$ _POST不会发送空复选框组

问题描述：

I have been working on a contact form for a website and I got this problem: I have 4 checkboxgroups, every each of them have at least 3 checkboxes that are available to check. We don't want them to be required to send the email. So the code is this:

$CheckboxGroup1 = array();
if(isset($_POST['submit'])){
    $name = $_POST['name'];
    $attending = $_POST['attending'];
    $CheckboxGroup1 = isset($_POST['CheckboxGroup1']) ? $_POST['CheckboxGroup1'] : 'Nothing checked';

HTML:

 <h4>What kind of set-up would you like?</h4>
 <p>Additional fees may apply for living room/specialty set-ups.</p>
 <p>
     <div class="inline-field">
         <label>
             <input type="checkbox" name="CheckboxGroup1[]" value="Living Room">
            Living Room
        </label>
        <br>
        <label>
            <input type="checkbox" name="CheckboxGroup1[]" value="Conference Room">
            Conference Room
        </label>
        <br>
        <label>
            <input type="checkbox" name="CheckboxGroup1[]" value="Other">
            Other (please specify at the end of the form)
        </label>
        <br>
    </div>
</p>

When none of the checkboxes is selected I get the message "Nothing checked" and when one of them is selected I get the value of it. The problem is when I select more than one, I get this in my email: What kind of set-up will you like?: Array (not the name of those selected).

I do not know what I have to change to make it work the right way.

Any help would be very much appreciated.

我一直致力于网站的联系表格，我遇到了这个问题：我有4个复选框组，每个每个人都有至少3个可供查看的复选框。我们不希望他们发送电子邮件。所以代码是这样的： p>

  $ CheckboxGroup1 = array（）; 
if（isset（$ _ POST ['submit']））{
 $ name = $ _POST [  'name']; 
 $ atte = $ _POST ['参加']; 
 $ CheckboxGroup1 = isset（$ _ POST ['CheckboxGroup1']）？  $ _POST ['CheckboxGroup1']：'没有选中'; 
  code>  pre> 
 
  HTML： p> 
 
 
 ＆lt; h4＆gt; 您想要什么样的设置？＆lt; / h4＆gt; 
＆lt; p＆gt;可能会对客厅/专业设置收取额外费用。＆lt; / p＆gt; 
＆lt; p＆gt; 
＆lt; div  class =“inline-field”＆gt; 
＆lt; label＆gt; 
＆lt; input type =“checkbox”name =“CheckboxGroup1 []”value =“Living room”＆gt; 
 Living room 
＆lt; / label＆gt  ; 
＆lt; br＆gt; 
＆lt; label＆gt; 
＆lt; input type =“checkbox”name =“CheckboxGroup1 []”value =“会议室”＆gt; 
会议室
＆lt; / label＆gt; \  n＆lt; br＆gt; 
＆lt; label＆gt; 
＆lt; input type =“checkbox”name =“CheckboxGroup1 []”value =“Other”＆gt; 
其他（请在表格末尾注明）
  ＆lt; / label＆gt; 
＆lt; br＆gt; 
＆lt; / div＆gt; 
＆lt; / p＆gt; 
  code>  pre> 
 
 如果没有选中任何复选框，我会得到 消息“没有检查”，当其中一个 他们被选中我得到它的价值。 问题是，当我选择多个时，我会在我的电子邮件中看到：
 您想要什么样的设置？：数组 strong>（不是所选项的名称）。 p  > 
 
 
我不知道我需要改变什么以使其以正确的方式工作。 p> 
 
 

非常感谢任何帮助。 p> 
   DIV>

答

you have to change below line

Your code

$CheckboxGroup1 = isset($_POST['CheckboxGroup1']) ? $_POST['CheckboxGroup1'] :  'Nothing checked';

Change it to

if( isset($_POST['CheckboxGroup1']))
{
 $CheckboxGroup1 =implode(", ",$_POST['CheckboxGroup1']);
}
else{
  $CheckboxGroup1="Nothing checked";
}

答

You cannot print array with echo. Echoing array will give you string Array. Simple way in your case to get array values is to use implode:

echo implode(', ', $yourArray);
